PV Fed High Frequency Inverter with Constant DC-Link Voltage for Load Application

In order to reduce leakage currents and streamline authority, power factor correction (PFC) converters are typically operated at low frequencies, which calls for large inductors. A separated, non-resonant, single-stage DC-DC converter with variable frequency control is the suggested system's main component. This system has the potential to guarantee a steady dc-link voltage regardless of power flow is one of its major aspects, which raises the performance of the model. Photovoltaic (PV) modules power supply is balanced by the voltage equalizer, which also stops bypass diodes from bypassing any shaded components in a string. As a result, tight output regulation in low output voltage applications only requires a small output capacitance. The power dissipation caused by swapping at zero voltage and current are reduced by the proposed system. These benefits are confirmed by a prototype that maintains ZVS throughout electricity and voltage for efficiency and good power factors. By utilizing increased leakage currents, this transformer profit from significantly lower passive circuit components for energy conversion and EMI filtration. MATLAB modelling is used to complete this project.
